The Investigation of the Relationship Between Shoulder Izokinetic Strength and Ball Shoot Velocity in Elite Handball Players

This study was conducted to investigate the relationship between isokinetic strength and ball shoot velocity in elite handball players. Thirteen voluntary male handball players, who were playing in the handball super league, participated in the study. The isokinetic shoulder internal (IRPT) and external (ERPT) rotation peak torques (60°s-1, 240°s-1 and 400°s-1) of the handball players’ by isokinetic dynamotres, their ball shooting velocitys were determined by radar device. Spearman Correlation Analysis was utilized to determine the relationship between isokinetic shoulder strength and ball shooting velocity. As a result of the statistical analysis, it has been found that there is a positive relationship between a IRTP (60°s-1, 240°s-1 and 400°s-1) and the ball shooting velocity while not moving and IRPT (240°s-1) and the ball shooting velocity while moving. As a result, significant relationship has been detected between the upper extremity strength used in handball and ball shooting velocity which has a direct effect on the individual and team performance of the athletes. In particular, coaches may be advised to include tranining on the strengthening of internal rotator muscles (M. Subscapularis, M. Delteiod Aterior, Pectoralis Major etc.) affecting ball velocity during internal rotation
